rnansrna MECHANISM.

Specification of Letters Patent.

Patented May 2, 192 2.

Application filed January 5, 1920. Serial No. 849,510.

tion with the accompanying drawings,:is a I specification, like characters on the drawings representing like parts. I I

This invention pertains to improvements in transfer mechanisms, and more; particularly, though not exclusively, to transfer mechanisms for use in connection with preparing batches of. stock or other textile mills.

One: use for which. the preferred embodidescribed is particularly adapted is. shown diagrammatically in my copending. application directed to improvements in apparatus, installations and methods for use in treating textile stock, Serial No. 349,508, filed Jan. 5, 1920.

In the drawings,.which show, a preferred form ofone embodiment of my invention Figure 1 is a side form of truck and parts carried thereby;

Fig. 2 is an end elevation of the appa ratusfshown in Fig. 1, in connection withv a preferred form of apparatus for facilitating discharge of a load of material from the truckrand Figs.,3 and 1 show details of a portion of the discharge mechanism shown in Fig. 2

and. illustrate two different steps in the operation of such mechanism.

Referring to the ferred form of my invention selected for illustrative purposes, I have shown a track including rails 5, truck including wheels 6 journalled. in suitable bearings attached to a truck frame 7 which preferably carries a scale having a base 8 and a weighing platform. 9, on which is in turn mounteda floorlO, preferably through the medium of channel irons 11. Inthe preferred formgof my invention, I havemounted on the floor and channel irons 10 and 11, the

framework; including. end members 12, 12,

which may be and preferably are connected the apparatusby a side brace member 13. r

Cooperating with the before-:described mechanism, I preferablyiprovide, a. reni0V- for use in woolen support 19 elevation ofa preferred drawings and to-the preon which is mounted. a

' erably engaging position 26 connected to thelever Qt-by any suitable able, bottomless container or box 1 1, which may be carried on wheels or rollers 15, 15 adapted to roll on tracks 16, 16 carried by the end frames 12, 12 of the apparatus.

The truck with the scale carried thereby, the boxv floor carried by the scale, and the bottomless box above the floor may be wheeled along the track 51 to or from any desired point wherethe box may be filled with stock,preferably through a trap door in the floor above. To prevent the bottomless box from rolling off. the truck, I may provide any suitable retaining mechanism, herein shown as spring-pressed detents 17 adapted to project through the rails 16-, 16 and to chock one or more of the wheels 15. To facilitate emptying of the stock carried by the apparatus hereinbeforedescribed I preferably provide means for moving the bottomless box off the truck and'over anopening, herein shown asa hole or trapdoor 18 in the floor on which the rails 5 are carried, such means preferably providing a adapted to carry rails 20 in alignment with the rails 16, 16 onto which the wheels 15 may pass so as to bring the bottomless box into the position shown in dotted lines in Fig. 2.

To prevent tipping ofthe truckesupported apparatus during the transference of the bottomless boxfrom the truck to the dumping support, I may providethe' truck. with means adapted to steadythe same laterally during the transfer operation, herein typified by abutting means preferably including rollers 21 carried by the floor 10, or parts connected thereto carried by the platform of the scale, cooperating with a com-plemental abutment 22, ary and carried by the floor. This mecha-- nism prevents tipping of the truck and especially of the parts carried by the scale platform. To hold the truck with the rails 16, 16 in alignment with the rails 20, I prefprovide longitudinal positioning means, herein typified by a rockshaft 23-carrying a rocking lever 24 providing anotch at the upper, end thereof adapted to engage with opposite sides of a part carriedby the truck, herein shown as a strap 25 secured to: one oftheend frames .12. The lever 24: may conveniently be rocked into engaging or disby a. foot-controlled lever connecting means 27 7 gaging opposite sides of the strap 25 are so'thatthe truck is free to be tionof the arrow shown in drawn out of engagement with the strap 25, pushed along the rails. The weighing operation is preferably performed during the filling of the box While over the while the truck-carried apparatus is not in alignment .with the discharge facilitating apparatus so that the functioning of the scale will not be interfered with because of the engagement of the rollers 21 with the abutment 22. I

When the parts are in the position shown in Fig. 2, and the truck is held against tipping movement or against movement lengthwise of the rails 5, movement of the bottomless box from the position shown in full lines on the rails 16, 16 to the po sition shown in dotted lines on the rails '20 may, if desired, be facilitated by any suitable mechanism, but preferably by man ually operable means herein typified by a chain 28 passing at one end over a sprocket 29 carried by a relatively short shaft 30, and at the other end by a sprocket '31 which may conveniently be mounted on a *shaft 32 of suflicient length to extend to the I other end of the support'19 where similar chain and sprocket mechanism cooperating with parts preferably similar to those hereinafter described maybe adapted to engage and apply force to move the opposite end of the bottomless box.

I preferably mount on the shaft 32 a handwheel 33 to facilitateturning of the same and the sprockets carried thereby.

The chain 28 preferably carries a hook 34 adapted to engage projecting means typified by the pin 35 on the bottomless box and, when the hand-wheel 33 is turned in a clockwise direction as viewed in Fig. 2, the hook 34 will engage the'pin 35 and on continued rotation in a clockwise direction the handwheel 33 will move the hook, the pin, and consequently the bottomless box, in the direc- Fig. 3, the position of the box shown in dotted lines in Fig.

2 being ultimately reached, at which time, there being nothing under the bottom of the box the contents thereof will drop through the opening 18 into the bin or other receiver beneath.

After the discharge operation, the direction of'rotation of the hand-wheel 33 will be changed so that it will turn in a contraclockwise direction, at which time the pivoted latch 36 will come into operation to push against the pin 35 and return the now empty bottomless box to its initial position on the truck.

floor carried by the truck,

28, the latch 34 and cooperating parts de- .36, and Imayconveniently perform this by providing the latch, which is pivoted: at 37, witha lever arm 38 pivoted to the latch at 39 and cooperating with a stop 40 adapted to limit swinging movement of the lever arm 38 relative to the latch in one direction. On the sprocket29,.I provide a pin 41 adapted to engage the lever 38 and, just before the parts assume the positionshown in Fig.4, to rock the latch 36 away from the pin 35..

I prefer to mount 'thelever 38in pivoted relation to the latch 36, so that during the bottomless box removing. operation, shown in Fig. 3, continued movement of the parts in the direction shownin Fig. 3 will not result in interference of the pin 41 with the lever'38, the latter being permitted to swing V out of the way ofnthe pin without moving the latch 36, which during this operation is preferably in contact with a stop 42.

It will be-understood that the transfer faoilitating mechanism typified v.by the chain 7 scribed above is preferably provided in duplicate, so that both ends of the bottomless box may be engaged during the transfer operation, the pin 35 also being'in-duplic'ate asshowninFig. 1. i V I The frame 7 of the truck maybe pro vided with extensions 50- to provide handles 51, so that the truck andpa rts carried there by may be conveniently pushed or pulled without the pushing or pulling force being directly applied to the parts carried on the scale platform.
